Abstract

         Inguinal hernia is a common disease among patients attending in general surgery clinic. Each year, around 80 to 100 hernia cases were treated in Nongphai hospital, Phetchabun province. The current anesthesia practices for inguinal hernia surgery are categorized into three procedures: (1) local anesthesia, (2) spinal anesthesia, and (3) general anesthesia. This study aimed to compare between the local and spinal anesthesia with regard to patient’s characteristics, operation time, length of hospital stay, complications either during or early post-operation, and the cost of the anesthesia. We collected and reviewed all medical records of the inguinal hernia patients who were operated in Nongphai Hospital from October 2004 to September 2013. Statistical analysis was conducted by using percentage, Chi-square test, Student t-test, Fisher’s exact test, and Mann–Whitney U test. Altogether 290 patients were included in the study. They were male, aged between 15 to 97 years old. It was found that the operations using local anesthesia had significantly less operation time; and the patients had more experience of the full bladder during surgery. In contrast, there was no significant difference in the decrease in blood pressure during surgery and the length of hospital stay. The cost of spinal anesthesia was three to four times higher than that of local anesthesia. In conclusion, the surgical procedures applying local anesthesia spend shorter time and save cost when compare to spinal anesthesia in inguinal hernia cases
